This paper reviews the current position of studies on the epidemiology of bipolar affective disorder.
A disorder that cannot be recognized until sometime after its onset poses special difficulties for epidemiological study.
These are discussed and attempts made to solve them.
Community psychiatric surveys suggest a morbid risk of bipolar disorder of around 2-2.5%, but probably include many false-positives.
Studies of treated cases indicate a morbid risk of 0.5%, but will miss untreated cases.
It is probably reasonable to suggest a compromise value of 1-1.5% ; bipolar disorder is thus still a rare condition.
It is possible to quantify the unipolar-bipolar conversion rate, which is of the order of 5%, and it is of particular interest that female sufferers have proportionately fewer manic episodes.
Age at onset, possible cohort phenomena, comorbidity, and sociodemographic correlates are discussed.
